Hello there,
I have a 4G SIM overseas at my grandparent's country running in a Hotspot/LTE Dongle. I am not sure if it runs any CG-NAT yet, (I think it might), however I am sure it does not have a static IP (and 99% sure it has CG-NAT since LTE mostly does/dynamic IP types). What I want to do is, an application only runs if it thinks I am connected to that ISP's LTE Dongle (the exact device). How can I fake the application into thinking I am indeed 'connected' to that device while here I am overseas in Sydney.
I think I asked this before here and someone suggested me a VPN connection to the dongle. But then, (assume it DOES have a CG-NAT, as I am sure it does), I can't setup a publicly accessible VPN server because of the CG-NAT. I cannot port forward or anything. But look at this; weirdly, the dongle itself does have options to Port Forward and says we can do it for "games and other stuff". So I am confused there, would port forwarding even work?
Also, I read about accessing the server via reverse tunnelling, how would I do that? What exactly are the specifics I need? But then, if the LTE Dongle is behind this CG-NAT firewall, how will the SSH tunnel even send packets INTO the LTE dongle in the first place to even connect? I'm fairly newbie to this, so need help!
Or, if there is a better way to connect and fake the application into thinking I am connected to the 4G Dongle, from overseas, I'd love to hear about it!
Thanks.
